It's very unlikely that they would allow a 1st Class relic to be placed in a Rosary.  Those usually must be in special reliquaries and should be accompanied by a seal and a certificate of authenticity.  What you have is likely a 3rd or 4th class relic.  So you would not refer to it as her.

Latin inscription reads "Ex Capsa S. G." ... meaning from her coffin or tomb.

Thanks, Lad. I know you are learned because didn't you go to Seminary under Bishop Williamson like Matthew did? You obviously know Latin, but do you know Greek and Hebrew as well? When I was a new convert I wanted to learn Latin, but now I don't think I need to learn Latin, except perhaps for the prayers of the Mass, because I am not a priest. It would make more sense for me to learn Spanish so I could speak with the good Hispanic people who live in my neighborhood

There's always value in learning Latin ... since it's long been the language of the Church, and anything that gets us closer to knowing the mind of the Church can be helpful.  Greek and Hebrew are admittedly more of a luxury.  I know ancient Greek well, but my Hebrew is practically non-existent anymore.  I haven't read any in about 30 years.  I was at the SSPX seminary under Bishop Williamson, but was there just a few years before Matthew's time.

Doesn't JayneK know Hebrew? Have you ever ask a converted Jєω for help with your Hebrew? Didn't Saint Jerome learn how to speak and write in Hebrew from a Jєωιѕн Rabbi before he examined all the ancient texts wrote Vulgate which the Church declared was without error? Like Bishop Williamson had that Rabbi speak to his seminarians (and act which scandalized many of the faithful who are wears of the Jєωs). Then you could be a real scholar.

But I just found my old Latin Textbooks and will look at them when I get the chance. I have Wheelock's Latin for classical Latin, and I have A Primer of Ecclesiastical Latin for Church Latin. I do remember once reading about a priest who taught children; he said  Latin was for everyone, but Greek was only for the gifted. I wonder what he would say about Hebrew? I once heard that Hebrew was the original language and it was in Hebrew that Adam spoke to God in the Garden of Eden. But that may be hearsay, and anyway the substance of all languages are the same, is that right? It is only the accidents that differ, is that right? Because all men live in the same world and they give names to the same creatures, is that right? And the forms of those creatures are in the mind of God, is that right? And we give names to these forms, but the names are always inspired by the good God, is that right? So the names we give creatures are always correct, is that right? Even in Chinese, is that right? Even if we do not know what we are saying, God knows all, is that right? Even the witch-doctors, is that right?

Sometimes I believe the world is a never-ending game of chess played between the good God and satan. And after each game (which God always wins at the first move), Satan examines the game and tries to learn how to defeat the strategy of the good God. Then another game begins and the devil uses his strategy which he thinks will win. But he loses on the first move, but he thinks there is a game going on and that he has a chance of winning. And each game goes further and further and gets more and more intricate with more and more moves until the end of the world. but in reality there was only one move, the Blood of Christ.
But are the games real? Yes, but I do not understand the mystery.
